1 Claim. (Cl. 81-15) This invention relates to an improved pin-crimping tool or the like.

Television tubes or the like are provided at one end with projecting electric terminals adapted to be received within provided electric sockets. Each terminal consists of a tubular connector into which an electric wire extends from the interior of the tube. This wire is soldered in place within the tubular connector. The soldering may come loose and this necessitates a re-soldering or the tubular connector may be pinched against the wire securely enough to establish the required electrical connection. This invention relates to the provision of a crimping tool which is provided for the specific purpose of crimping or pinching the tubular connector against the electric wire received therein.

An object is to provide a tool of the character described which is simple, inexpensive, and operable to eectively accomplish its intended purpose and which is so designed that it is handy to use and is so constructed as to be capable of use by any mechanic to securely crimp the tubular connector against the electric wire inserted thereinto.

Another object is the provision of a tool of the character set forth which is provided with a socket or aperture adapted to receive a tubular connector and is also provided with crimping means adapted to be manually actuated to crimp the tubular connector received within the socket against the side wall or anvil portion of the socket to squeeze it against an electric wire inserted within the connector.

A further object is the provision of a tool of the character set forth having an elongate handle portion provided at one end with a socket extending thereinto which socket is adapted to receive a tubular connector. The tool is also provided with a swingably supported blade or crimping element which is adapted to be swung to enter the socket and crimp a connector pin received therein or to be swung to be withdrawn from the socket to open the same to receive a connector pin.

The free end of the blade is shaped to serve the purpose of a screw driver blade and the free end of the handle is shaped to serve the purpose of the opposed jaws of a wrench element.

Other objects, advantages, and meritorious features will more fully appear from the following description, claim, and accompanying drawing wherein:

Fig. 1 is a side elevation of a tool embodying my invention;

Fig. 2 is an enlarged sectional view of the pin-receiving end of the tool showing the socket of the tool open and with a connector pin disposed therein;

Fig. 3 is an enlarged sectional view taken on the same line as Fig. 2 showing the crimping means actuated so as to crimp the pin received within the socket of the tool;

Fig. 4 is a cross sectional view taken on the line 4--4 of Fig. 2; and

Fig. 5 is an enlarged cross sectional view taken on the line 5-5 of Fig. 3.

The tool of this invention comprises a handle portion 10. This handle portion is shown as of an elongate shape and is provided at one end with a socket 12. The socket is of a size to receive a connector pin of a television tube. The tubular connector pin is indicated by the numeral 14. The tube provided with the pin is indicated by the numeral 16. The tubular connector 14 is fitted with an electric wire 18 which extends thereinto and which is soldered in place. At times the soldering comes loose and it is necessary to re-solder it or to crimp the pin against the wire so as to hold it securely in position. This tool is provided for the purpose of crimping the tubular connector pin 14 against the wire 18.

The handle portion 10 is provided along one side with a channel or groove 20 which is shown in Figs. 2-5 as entering into the pin-receiving socket aperture 12. This groove or channel preferably extends for the length of the handle. A blade 22 is pivoted at 24 within this groove 20 as shown particularly in Figs. 2, 3, and 4. As shown in the gures, the blade is pivoted within the channel 20 off center the center line of the blade so that when the blade is swung to the angular position shown in Fig. 2, the blade does not enter into the socket 12. When the blade is folded down toward the position shown in Fig. l, the rounded end of the blade enters the socket as shown more particularly in Fig. 3 and a tubular connector received within the socket is crimped against the wire disposed within the connector. This is shown particularly in Figs. 3 and 5. That side Wall of the socket opposite the blade 22 serves as an anvil against which the tubular connector is crimped.

That end of the handle opposite the socket end is provided with a pair of opposed jaws 26 which enables the same to serve the purpose of a fixed jaw wrench. The free end of the blades 28 is shaped to serve as a screw driver blade so that the tool serves a multiplicity of uses.

What I claim is:

l A tool for longitudinally crimping hollow cylindrical pin terminals of multi-terminal electronic devices or the like comprising, in combination: a handle having an end portion to be telescoped over the pin terminal to be crimped with such portion suciently slender to allow rotatable positioning upon the pin between other closely adjacent terminal pins, said portion of the handle provided with a blade-receiving slot projecting thereinto from one side and extending from the outer end in a direction lengthwise of the handle, a flat blade pivoted at one end within the slot at said end portion of the handle to be swung about said pivot to and from a position of substantial alignment within the slot and to and from a position substantially perpendicular with respect to the slot, said end portion of the handle provided with a cylindrical pin-receiving socket extending thereinto from the outer end parallel the slot and within which the pin to be crimped is telescoped, said socket communicating throughout at least a portion of its depth with the bottom of the slot, said socket having a diameter greater than the width of the slot and just exceeding the diameter of a terminal pin received therewithin to closely contain and prevent lateral bulging of the pin during crimping, the extremity of the pivoted end of the blade being shaped so that when the blade is received substantially in alignment within the slot such end portion of the blade projects into and across the socket and when the blade is swung upwardly out of the socket and is disposed substantially perpendicularly With respect to the slot such end portion of the blade is substantially withdrawn from the socket.
